Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application will be further described in detail with reference to the accompanying drawings.

In order to facilitate understanding of the technical processes of the embodiments of the present application, some terms referred to in the embodiments of the present application are explained below:

block Chain (Block Chain): the method is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The blockchain is essentially a decentralized database, which is a string of data blocks associated by cryptography, each data block containing information about a network transaction for verifying the validity (anti-counterfeiting) of the information and generating the next block, each block containing a timestamp and a link to the previous block. In a narrow sense, a blockchain is a distributed ledger of data blocks assembled in a sequential manner into a chain data structure in chronological order and cryptographically secured as non-falsifiable and non-forgeable, i.e. the data in the blockchain will be irreversible once recorded.

Alliance Chain (Alliance Chain): refers to a block chain whose consensus process is controlled by preselected block link points. The block chain account book can limit the reading authority only inside the coalition members and can also provide reading capability to the outside. In the alliance chain, all or part of functions are opened only for the members of the block chain link points in the chain, and each block chain link point in the alliance chain can customize read-write permission, query permission and the like based on requirements.

Consensus Mechanism (Consensus Mechanism): the block chain system is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes. In the blockchain system, the verification and confirmation of the transaction can be completed in a short time through the voting of a special node or all nodes. Wherein, if a plurality of nodes with irrelevant benefits can achieve consensus on a transaction, all nodes in the system can be considered to achieve consensus on the transaction.

Smart Contract (Smart Contract): is a computer protocol intended to propagate, validate or execute contracts in an informational manner. Each node in the blockchain system can automatically execute a contract program according to a specific condition, can operate data stored in the chain, and is an important way for a user to interact with the blockchain and realize business logic by using the blockchain. The goal of smart contracts is to provide a secure method over traditional contracts and to reduce other transaction costs associated with the contracts, which allows for trusted transactions that are traceable and irreversible without third parties.

The embodiment of the application provides a safety risk information management method based on a block chain, which can determine a second user identifier bound with a first user identifier and send prompt information to a second terminal corresponding to the second user identifier when monitoring safety risk information sent to the first terminal corresponding to the first user identifier, so that the second user can know that the first user receives the safety risk information, and the first user is reminded.

For example, in the scenario of preventing telecommunication fraud, the telecommunication fraud refers to a criminal who creates false information to set a fraud bureau by means of telephone and short message, conducts remote and non-contact fraud on a victim, and induces the criminal to pay money or transfer money for the criminal.

In order to prevent telecommunication fraud, a group with relatively weak security consciousness, such as middle-aged and elderly people or teenagers, is used as a guardian, and the family members of the group are used as protectors. When the fact that the guarded receives the fraud short message or the fraud telephone is identified, prompt information is sent to the guarder so that the guarder helps the guarded to identify the fraud.

401. and the second terminal sends a monitoring target registration request to second node equipment in the block chain system.

The first user possesses a first terminal for logging in the first user identification, and the second user possesses a second terminal for logging in the second user identification. The first terminal and the second terminal are respectively in communication connection with second node equipment in the block chain system, and the second node equipment provides services for the first terminal and the second terminal. And when the second user needs to monitor the security risk information received by the first user, sending a monitoring target registration request to the second node equipment through the second terminal.

The second node device is any node device in the blockchain system. The second node device can establish communication connection with the terminal to provide service for the terminal, such as realizing functions of registering and monitoring target user identifiers, establishing binding relations among the user identifiers, sending messages to the terminal, and the like. Optionally, the second node device is an instant messaging server of an instant messaging client, the first user may log in the instant messaging server through the instant messaging client based on the first user identifier, the second user may log in the instant messaging server through the instant messaging client based on the second user identifier, and the instant messaging server may establish a binding relationship between the first user identifier and the second user identifier.

In one possible implementation manner, the monitoring target registration request carries a first user identifier that requests to be registered as the monitoring target user identifier, and a second user identifier that requests to be bound with the first user identifier. The monitoring target registration request is used for indicating the second node equipment to establish a binding relationship between the first user identification and the second user identification, and registering the first user identification as the monitoring target user identification.

The first user identification is used for representing the identity of the first user, and the second user identification is used for representing the identity of the second user. The user identifier may be a user account, a telephone number, a user nickname, an email, or the like. The monitoring target user identifier represents a user identifier to be monitored in the block chain system, and when the first user identifier is registered as the monitoring target user identifier, the block chain system monitors the first user identifier so as to manage the security risk information received by the first user identifier.

The binding relationship refers to binding between a first user identifier and a second user identifier, wherein the first user identifier is a user identifier to be monitored, the second user identifier is a user identifier to be prompted, and the binding relationship represents that: and monitoring whether the first user identification receives the safety risk information, and prompting the second user identification when the first user identification receives the safety risk information.

In another possible implementation manner, the second node device provides a binding entry for the second terminal, and the second terminal sends a monitoring target registration request to the second node device through the binding entry. The binding entry may be a client installed on the terminal, an applet in the client, a website in a browser, or a public number of a service class.

And the second terminal displays at least one user identifier associated with the second user identifier when detecting the triggering operation of the registration button based on the monitoring target registration interface, generates a monitoring target registration request comprising the first user identifier and the second user identifier when detecting the triggering operation of the first user identifier in the at least one user identifier, and sends the monitoring target registration request to the second node equipment.

The monitoring target registration interface can be an interface provided by a public number, and the public number has the functions of binding the user identifier, managing the safety risk information received by the user identifier and the like. For example, as shown in fig. 5, a public security department works together with an application client to create a public number 51 that can provide anti-fraud services, and a user concerning the public number 51 can establish a binding relationship between user identifications through the public number 51.

As shown in fig. 6, the second terminal displays a public number interface 61, the public number in the public number interface 61 has a function of managing security risk information, and a "friend-cheat-prevention" button 611 is included in the public number interface 61. When the clicking operation of the button 611 by the second user is detected, a function introduction interface 62 is displayed, and a "bind friends" button 621 is included in the function introduction interface 62. When the clicking operation of the second user on the button 621 is detected, a buddy list interface 63 of a second user identifier currently logged in by the second terminal is displayed, where the buddy list interface 63 includes a plurality of user identifiers associated with the second user identifier. When the click operation of a second user on the user identifier 1 is detected, the user identifier 1 is used as a first user identifier to be bound, and the second terminal sends a monitoring target registration request carrying the first user identifier and the second user identifier to second node equipment according to the click operation.

402. And when receiving the monitoring target registration request sent by the second terminal, the second node equipment sends the monitoring target registration request to the first terminal corresponding to the first user identification.

When receiving a monitoring target registration request sent by a second terminal, a second node device determines that a request carried in the monitoring target registration request is registered as a first user identifier of a monitoring target user identifier, and sends the monitoring target registration request to a first terminal corresponding to the first user identifier.

In a possible implementation manner, the second node device generates a registration link corresponding to the monitoring target registration request according to the monitoring target registration request sent by the second terminal, sends the registration link to the first terminal based on the second user identifier, and receives the registration link by the first terminal based on the first user identifier.

403. And when receiving the monitoring target registration request sent by the second node equipment, the first terminal sends a registration confirmation message to the second node equipment.

When receiving the monitoring target registration request, the first terminal may send a binding acknowledgement message to the second node device, where the binding acknowledgement message is used to indicate that the monitoring target registration request of the second user identifier is accepted.

In one possible implementation manner, the first terminal displays a monitoring target registration interface, and the monitoring target registration interface comprises a registration prompt message and a confirmation button. And when the first terminal detects the trigger operation of the confirmation button based on the monitoring target registration interface, sending a registration confirmation message to the second node equipment.

The registration prompt message is used for prompting that the first user identifier is registered as a monitoring target user identifier, and the confirmation button is used for confirming establishment of a binding relationship between the first user identifier and the second user identifier and registering the first user identifier as the monitoring target user identifier.

Optionally, the monitoring target registration interface further includes a reject button, where the reject button is configured to reject establishment of a binding relationship between the first user identifier and the second user identifier, that is, reject registration of the first user identifier as the monitoring target user identifier.

In another possible implementation manner, the first terminal receives a registration link corresponding to the monitoring target registration request sent by the second node device based on the first user identifier, and when the second node device detects a trigger operation on the registration link, the first terminal displays a monitoring target registration interface.

For example, when the first terminal receives the registration link sent by the second user identifier based on the first user identifier, the interactive interface 64 of the first user identifier and the second user identifier is displayed, as shown in fig. 5, the registration link sent by the second user identifier is included in the interactive interface 64. When the clicking operation of the first user on the registration link is detected, the monitoring target registration interface 65 is displayed, and the confirmation button 651, the rejection button 652 and the registration prompt message are included in the monitoring target registration interface 65. When the clicking operation of the first user on the confirmation button 651 is detected, the first terminal sends a registration confirmation message to the second node device.

It should be noted that, in the embodiment of the present application, only the first terminal receives the monitoring target registration request of the second terminal and sends the registration confirmation message to the second node device is taken as an example for description. In another embodiment, the first terminal may further reject the monitoring target registration request of the second terminal, and send a registration rejection message to the second node device, where the registration rejection message is used to indicate that the monitoring target registration request of the second user identifier is rejected.

It should be noted that, in the embodiment of the present application, only the second node device sends the registration link to the first terminal as an example for description. In another embodiment, the second node device generates a registration link corresponding to the monitoring target registration request according to the received monitoring target registration request, sends the registration link to the second terminal, and sends the registration link to the first terminal by the second terminal. For example, when the second terminal receives the registration link, the registration link may be sent to the first terminal in a form of a social account or a short message.

404. When receiving a registration confirmation message sent by a first terminal, a second node device establishes a binding relationship between a first user identifier and a second user identifier, registers the first user identifier in a blockchain, and broadcasts the first user identifier to other node devices in the blockchain system.

And the second node equipment receives the registration confirmation message sent by the first terminal, establishes the binding relationship between the first user identification and the second user identification, registers the first user identification as a monitoring target user identification in the block chain, broadcasts the first user identification to other node equipment in the block chain system, and keeps the block chain of each node equipment synchronous. The first user identification receiving the monitoring target registration request is the user identification to be monitored, and the second user identification sending the monitoring target registration request is the user identification to be prompted.

In one possible implementation, the second node device generates a second block including the first user identifier, broadcasts the second block to other node devices in the blockchain system, so that the plurality of node devices in the blockchain system perform consensus verification on the second block, and records the second block in the blockchain when the second block passes the consensus of the plurality of node devices in the blockchain system.

Optionally, the process of generating the second block by the second node device may include: the last block in the block chain is called as a previous block, the second node device can acquire the information of the previous block from the block chain, so that a block head characteristic value of the previous block can be generated based on the information of the previous block, characteristic value calculation is performed on information such as a first user identifier and the like which needs to be stored in the second block, a block main body characteristic value of the second block is obtained, and further, the second node device can store the block head characteristic value of the previous block and the block main body characteristic value of the second block to a block head of the second block, and store the information such as the first user identifier and the like to a block main body of the second block, so that the second block is generated. Therefore, the previous block and the second block are related by the block head characteristic value of the previous block, so that the aim of connecting blocks in series in a block chain can be fulfilled, and the next block can be used for verifying whether the previous block is correct or not. It should be noted that the above description of the block generation process is only an exemplary description of one block generation method, and the embodiment of the present application does not limit which block generation method is specifically adopted.

And after the second node equipment generates the second block, verifying the second block through a consensus mechanism. The blockchain system can identify the second block to determine whether the information in the second block is accurate, i.e., verify the information in the second block. In a possible implementation manner, after the second node device generates the second block, the second block may be broadcast to other node devices, and the other node devices may verify the second block and broadcast the verification result in the block chain system, respectively. The target ratio may be set by a block chain system, which is not limited in the embodiment of the present application. The consensus process can be implemented based on a consensus mechanism, for example, the consensus mechanism can be a workload proving mechanism, a rights and interests proving mechanism, a shares authorization proving mechanism, and the like. It should be noted that the above-mentioned consensus process is only an exemplary description, and the embodiments of the present application do not limit this.

It should be noted that, in this embodiment, only one first user identifier is taken as an example for description, in another embodiment, the second node device may obtain a plurality of first user identifiers that are requested to be registered as monitoring target user identifiers, package the plurality of first user identifiers obtained within a period of time, generate a second block, perform consensus on the second block by the blockchain system, and after the second block passes the consensus, synchronize the plurality of first user identifiers in the second block to any node device in the blockchain system.

In another possible implementation manner, the second node device encrypts the first user identifier by using a preset encryption algorithm, and broadcasts the encrypted first user identifier to other node devices in the blockchain system, so that the other node devices register the encrypted first user identifier in a corresponding blockchain, and the blockchain of each node device keeps synchronous.

Since each node device in the block chain system can acquire the first user identifier stored in the block chain, and the first user identifier is the privacy data of the first user such as the name, the telephone number, the e-mail box, the identification number and the like, in order to ensure the privacy safety of the first user, the second node device uploads the encrypted first user identifier to the block chain, and the privacy data of the user are prevented from being leaked.

The preset Encryption Algorithm may be DES (Data Encryption Algorithm), AES (Advanced Encryption Standard), and the like, and the embodiment of the present application is not particularly limited.

It should be noted that, in the embodiment of the present application, only the first terminal sends the registration confirmation message to the second node device as an example for description. In yet another embodiment, the first terminal may further send a registration rejection message to the second node device. And if the second node equipment receives the registration rejection message sent by the first terminal, the binding relationship between the first user identification and the second user identification is not established, and the first user identification is not registered in the block chain. Optionally, when the second node device receives the registration rejection message sent by the first terminal, the registration rejection message is sent to the second terminal.

405. And the second node equipment sends a registration success message to the second terminal.

406. And when the second terminal receives the registration success message sent by the second node equipment, outputting the registration success message.

And when the second terminal receives the registration success message sent by the second node equipment, outputting the registration success message to remind the second user of successful registration. For example, as shown in fig. 6, the second terminal displays a public interface 66, and a registration success message is displayed in the public interface 66. The registration success message includes the registered user identifier, the registration time, and the like.

It should be noted that, in this embodiment, it is described by taking an example that the monitoring target registration request carries the first user identifier and the second user identifier, but in another embodiment, the monitoring target registration request only includes the first user identifier, and the second node device only needs to register the first user identifier as the monitoring target user identifier.

It should be noted that, in the embodiment of the present application, it is described that the user identifier to be prompted actively sends the monitoring target registration request, and the user identifier to be monitored receives the monitoring target registration request. In another embodiment, a monitoring target registration request may also be actively sent by a user identifier to be monitored, and the user identifier to be prompted receives the monitoring target registration request, which includes the specific steps of: and the second node equipment receives a monitoring target registration request sent by a first terminal corresponding to the first user identification and sends the monitoring target registration request to a second terminal corresponding to the second user identification. When the second node device receives the registration confirmation message sent by the second terminal, the binding relationship between the first user identifier and the second user identifier is established, the first user identifier sending the monitoring target registration request is registered as the monitoring target user identifier, namely the user identifier to be monitored, and the second user identifier receiving the monitoring target registration request is used as the user identifier to be prompted. In this case, the monitoring target registration request carries a first user identifier requesting registration as the monitoring target user identifier and a second user identifier requesting binding with the first user identifier. The process is similar to the above-mentioned step 401-406 and will not be described again.

703. And when receiving the monitoring target registration request sent by the second node equipment, the first terminal sends a registration confirmation message to the second node equipment.

704. When receiving a registration confirmation message sent by a first terminal, a second node device establishes a binding relationship between a first user identifier and a second user identifier, registers the first user identifier in a blockchain, and broadcasts the first user identifier to other node devices in the blockchain system.

The blockchain system stores an intelligent contract for managing security risk information, and the intelligent contract is a contract program automatically executed according to specific conditions. When the second node device registers the first user identifier as a monitoring target user identifier in the blockchain system, triggering an intelligent contract in the blockchain system, and executing subsequent operation by the node device in the blockchain system according to the intelligent contract.

The specific process of the second node device registering the first user identifier as the monitoring target user identifier in

step

701 and 704 is similar to that in step 401 and 404, and is not described herein again.

Fig. 8 is a flowchart of a method for monitoring target registration according to an embodiment of the present application, and with reference to fig. 8, the steps are as follows:

1. and the second terminal corresponding to the second user identification initiates a monitoring target registration request.

2. And judging whether the first terminal of the first user identification accepts or not. If the first terminal accepts the registration, the next step is executed; if the first terminal does not accept the registration, the registration fails and the process ends.

3. And registering the first user identifier as a monitoring target user identifier, finishing the registration and ending the process.

705. And the first node equipment in the block chain system collects communication information and identifies the safety risk information of the communication information.

The first node device is a node device in a block chain system, and has a function of collecting communication information, wherein the communication information can be a telephone or a short message, and the first node device is a server of an operator, a server of a mobile phone manufacturer, or a server associated with an application client having an authority of inquiring a call record or a short message record, and the like.

The first node device may acquire communication information between the terminals in real time or periodically, identify the acquired communication information, and acquire a receiver user identifier of the security risk information if the communication information is identified as the security risk information. The safety risk information refers to information which may cause harm to users, such as fraud calls, fraud short messages, marketing calls and the like. In the embodiment of the application, the user identifier of the receiver of the communication information acquired by the first node device is the first user identifier.

In a possible implementation manner, the first node device obtains a sender user identifier of the communication information, and if the security risk identifier library includes the sender user identifier, identifies that the communication information is the security risk information.

When the first node equipment acquires the communication information, the sender user identification corresponding to the communication information is acquired, a safety risk identification library stored in the first node equipment is inquired, and whether the sender user identification is included in the safety risk identification library or not is judged. If the safety risk identification library comprises the sender user identification, the sender user identification belongs to the safety risk identification, and the communication information is determined to be safety risk information; and if the safety risk identification library does not comprise the sender user identification, the sender user identification does not belong to the safety risk identification, and the first node equipment does not need to process the communication information if the communication information is determined not to be the safety risk information.

The safety risk identification library is used for storing user identifications for sending safety risk information. Optionally, the user receives the communication information through the terminal, when the user considers that the communication information is the security risk information, the user identifier of the sender of the communication information may be marked, when the first node device detects a marking operation performed by the user, the user identifier corresponding to the marking operation is determined, and the user identifier is added to the security risk identifier library, or when the number of times that the user identifier is marked is greater than a preset value, the user identifier is added to the security risk identifier library. Optionally, the first node device may construct the security risk identification library in a machine learning manner.

In another possible implementation manner, when the first node device acquires the communication information, it is identified whether the communication information includes the security risk keyword. And if the communication information comprises the security risk key words, determining that the communication information is the security risk information.

For example, the first node device may construct a security risk keyword library in a machine learning or manual tagging manner, where the security risk keyword library is used to store words belonging to security risk keywords. And when the first node equipment acquires the communication information, matching the communication information with the safety risk keyword library, and judging whether the communication information comprises words in the safety risk keyword library. And if the communication information comprises words in the safety risk keyword library, the communication information comprises safety risk keywords, and the communication information is determined to be safety risk information.

For another example, the first node device performs semantic analysis on the communication information through artificial intelligence to identify whether the text information or the voice information of the communication information includes security risk keywords.

706. And if the first node equipment identifies that the communication information is the safety risk information, matching the first user identification with the monitoring target user identification registered in the block chain, and generating prompt information in response to determining that the first user identification belongs to the monitoring target user identification.

When the first node device obtains the first user identifier of the security risk information, one or more monitoring target user identifiers registered in the block chain are inquired, and whether the one or more monitoring target user identifiers comprise the user identifier which is the same as the first user identifier or not is judged. When the first node equipment determines that the first user identification is the same as a registered monitoring target user identification, determining that the first user identification belongs to the monitoring target user identification, and generating prompt information at least comprising the first user identification; when the first node device determines that the first user identifier is different from any user identifier in the one or more monitoring target user identifiers, the first user identifier is determined not to belong to the monitoring target user identifier, and the security risk information is ignored and is not processed.

Wherein the prompt message is used to indicate that the first subscriber identity receives the security risk information.

In a possible implementation manner, when determining that the first user identifier belongs to the monitoring target user identifier, the first node device obtains a sender user identifier corresponding to the communication information, generates a prompt message including the sender user identifier and the first user identifier, and subsequently uploads the prompt message to the block chain, where the prompt message is used to indicate that the first user identifier receives security risk information sent by the sender user identifier.

In a possible implementation manner, the first user identifier encrypted by using a preset encryption algorithm is stored in the blockchain. Therefore, when the first node device monitors the safety risk information, the preset encryption algorithm is adopted to encrypt the receiver user identification of the safety risk information, and if the encrypted receiver user identification is the same as the encrypted first user identification, prompt information is generated.

Because the preset encryption algorithm adopted when the second node device encrypts the first user identifier is the same as the preset encryption algorithm adopted when the first node device encrypts the receiver user identifier of the security risk information, if the encrypted receiver user identifier is the same as the encrypted first user identifier, it can be determined that the receiver user identifier before encryption is the same as the first user identifier before encryption. Therefore, when the encrypted receiver user identifier is the same as the encrypted first user identifier, it may be determined that the receiver user identifier is the monitoring target user identifier, and then prompt information including the first user identifier is generated.

It should be noted that, in the above step 705-706, the security risk information sent to the first terminal corresponding to the first user identifier is monitored by the first node device in the blockchain system through identifying the communication information and matching the first user identifier with the monitoring target user identifier, so as to generate the prompt information. In yet another embodiment, other ways may be used to monitor whether the first subscriber identity receives the security risk information.

707. The first node device records the prompt information in the blockchain and broadcasts the prompt information to other node devices in the blockchain system.

When the first node device generates the prompt message, the prompt message is recorded in the blockchain, and the prompt message is broadcasted to other node devices in the blockchain system, and the blockchain of each node device keeps synchronous.

In one possible implementation manner, the first node device generates a first block including the hint information, broadcasts the first block to other node devices in the blockchain system, so that the plurality of node devices in the blockchain system perform consensus verification on the first block, and records the first block in the blockchain after the first block passes the consensus of the plurality of node devices in the blockchain system.

The process of generating the first block is similar to the process of generating the second block in step 404, and is not described herein again.

Optionally, the second node device may package a plurality of pieces of hint information obtained within a period of time, generate a first block, and perform consensus on the first block by the block chain system, where after the first block passes the consensus, the plurality of pieces of hint information in the first block may be synchronized to any node device in the block chain system.

708. And the second node equipment extracts the prompt information from the block chain and determines a second user identifier bound by the first user identifier.

When the second node device extracts the prompt message, it is determined that the first user identifier in the prompt message receives the security risk information, the second node device queries the established binding relationship, and determines a second user identifier bound with the first user identifier, where the second user identifier is a user identifier to be prompted.

In a possible implementation manner, the second node device queries whether the established binding relationship includes a user identifier that is the same as the first user identifier, and determines, according to the binding relationship, the second user identifier bound by the first user identifier if the binding relationship includes the user identifier that is the same as the first user identifier.

The second node equipment inquires at least one established binding relationship, each binding relationship comprises a user identifier to be monitored and a user identifier to be prompted, and the second node equipment inquires whether the at least one binding relationship comprises the user identifier which is the same as the first user identifier. And if the binding relationship comprises the user identifier which is the same as the first user identifier, the second node equipment establishes the binding relationship between the first user identifier and other user identifiers, and the second node equipment determines the second user identifier bound by the first user identifier according to the binding relationship.

Optionally, if the binding relationship does not include the user identifier that is the same as the first user identifier, which indicates that the second node device does not establish the binding relationship between the first user identifier and the other user identifiers, the second node device ignores the prompt message.

709. And the second node equipment sends prompt information to a second terminal corresponding to the second user identification.

And when the second node equipment acquires the second user identification to be prompted, determining a second terminal corresponding to the second user identification, and sending prompt information to the second terminal. The prompt message is used for prompting the first user identifier to receive the safety risk message. Optionally, the prompt message further includes a sender user identifier, and the prompt message is used to prompt that the first user identifier receives the security risk information sent by the sender user identifier.

1. any node device in the alliance chain system collects communication information, and when a fraud call incoming call is monitored, the next step is executed.

2. The node equipment of the fraudulent call is monitored and whether the called number is on the block chain of the alliance chain system is inquired. If the block is on the blockchain, executing the next step; if not, the flow ends.

3. According to the intelligent contract, each node device in the alliance chain system is informed that the called number receives a fraud call.

4. Each node device respectively judges whether the binding relationship includes the called number. If the binding relationship established by the node equipment comprises the called number, the node equipment executes the next step; and if the binding relationship established by the node equipment does not comprise the called number, the node equipment ends the process.

5. And the node equipment sends a prompt message to the terminal bound with the called number, and the process is ended.

710. And the second terminal outputs the prompt message when receiving the prompt message.

The prompt message may include a text prompt message or a voice prompt message. When the second terminal receives the text prompt message, displaying the text prompt message in an interface of the second terminal; and when the second terminal receives the voice prompt message, playing the voice prompt message in the second terminal.

Optionally, the prompt message may include the first user identifier, a sender user identifier of the security risk information, a receiving time of the security risk information, and the like.
